Please help and explain the outcome..Thanks so much
i hope this can help you.
Answer: k = 21
Step-by-step explanation:
3(7 + x) = 3x + k
21 + 3x = 3x + k
21 + 3x - 3x = 3x + k - 3x
k = 21
Answer:
12,345 tablets may be prepared from 1 kg of aspirin.
Step-by-step explanation:
The problem states that low-strength children’s/adult chewable aspirin tablets contains 81 mg of aspirin per tablet. And asks how many tablets may be prepared from 1 kg of aspirin.
Since the problem measures the weight of a tablet in kg, the first step is the conversion of 81mg to kg.
Each kg has 1,000,000mg. So
1kg - 1,000,000mg
xkg - 81mg.
1,000,000x = 81
x = 0.000081kg
Each tablet generally contains 0.000081kg of aspirin. How many such tablets may be prepared from 1 kg of aspirin?
1 tablet - 0.000081kg
x tablets - 1kg
0.000081x = 1
x = 12,345 tablets
12,345 tablets may be prepared from 1 kg of aspirin.
Whenever we divide a certain number by 10 or 100 or 1000... the decimal point of the number always moves to your left hand side.
for example: 25 or 25.00 is a number that has its decimal point after 5.
suppose we divide it by 10, the decimal point point moves as number of times as the number of zeros in the divisor. here, 10 has 1 zero. isn't it?
hence, decimal point moves 1 time or once to the left
2.500 or simply 2.5
on writing a percent as decimal..
we always have the divisor as 100.
number of zeros in 100 : 2
hence point moves 2 times or twice to the left.
25 / 100 = .25 or 0.25
on re-writing 0.25 as fraction, count the number of digits right to the point. it is 2 here.
hence there would be two zeros as well,i.e, 100
hence , 0.25 = 25/100
hope it helps you! :)
